OIL-CUP- Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed June 8,1906- Serial No. 320,895.

To all whom it may concern:

Be it known that I, LUDwIe O. SEBELIN, of Davenport, county of Scott, and State of Iowa, have invented a new and useful Improvement in Oil-Cups, of which the following is a specification.

This invention relates to lubricators of the type known as oil-cups, embodying a cup or chamber adapted to communicate with the bearing surfaces or parts to be lubricated and a lid or closure.

The invention has special reference to the form and arrangement of the lid; and it consists in mounting the same on the body of the cup, so that it may be swung transversely over the oil-chamber to close the same and combining with the lid a closing-spring acting to hold the lid in closed position and adapted to permit the lid to be swung laterally to expose the oil-chamber, whereby when the lid is released the spring will act to automatically and instantly swing the lid over the chamber in closed position.

The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved oil-cup, showing the lid in closed position. Fig. 2 is a top plan view of the same with the lid swung laterally to open position. Fig. 3 is a longitudinal sectional elevation on the line a a of Fig. 4. Fig. 4 is a sectional elevation on the line b b of Fig. 3.

Referring to the drawings, 1 represents the body of the cup formed with a cylindrical neck 2, containing an opening 8 therethrough constituting the oil-chamber, which neck is threaded, as usual, on its exterior to adapt the device for attachment to the bearing to be lubricated. At its upper end the neck is surrounded by an annular shoulder 1, flat on its upper side, which shoulder projects at one side, forming a horizontal extension 5, from which rises a pivot-pin 6. 7 represents a lid or closure in the form of a plate flat on its under side to cooperate with the flat upper surface of the annular shoulder and formed with an extension 8, having an opening therethrough to receive the pivot-pin 6, the arrangement being such that the lid may be swung laterally over the upper end of the cup on the pin 6 as an axis, thus closing the oil-chamber, or it may be swung free of the upper end of the cup to expose the oil-chamber, as shown in Fig. 2.

The lid is confined on the pivot-pin by means of the cap 9, fitting over the upper end of the pin and removably fastened thereto by means of a cotter-pin 10 or by other suitable means, the lower portion of the cap being enlarged internally to leave an annular space between it and the pin and having its lower edge seated against the upper side of the extension 8 on the lid, so as to hold the latter snugly against the upper end of the cup. A spiral spring 11 surrounds the pivot-pin in the annular space within the cap and has its upper end. connected with the cap, as at 12, and its opposite end connected with the lid, as at 13. In assembling the parts the spring is placed under tension in such manner that by its tendency to expand or unwind it will hold the lid yieldingly over the upper end of the oil-chamber, the closing movement of the lid being determined and controlled by a stop-lip 14, depending from the side of the lid and adapted when the lid is in closed position to encounter a flat surface 15 on the side of the annular shoulder.

The lid is provided on its upper side with a vertical projection 16, by means of which it may be swung laterally against the influence of the closing-spring when the lid is to be opened.

In the use of my improved cup t is applied by means of the threaded neck to the bearing or parts to be lubricated, so that the open end of the chamber will communicate with the bearing-surfaces. The closing-spring, applied in the manner described, will hold the lid yieldingly in closed position over the upper end of the oil-chamber, thereby preventing the entrance of dust or other foreign substances and the escape of the oil. When the supply of oil is to be replenished, the lid is swung to one side by pushing on the projection 16, which action will overcome the closing tendency of the spring. When the requ site quantity of oil has been introduced, the lid is released, and the spring will act to instantly and automatically swing the lid back to its former position over the end of the chamber and effectually close the same, the closing movement being limited by the lip 14 engaging the surface 15 on the annular shoulder.

It will be observed that my improved cup ably to the is of very simple construction, is self-closing and wholly free from such exposed relatively moving parts or joints as would likely be clogged by the accumulation of dust or mud and that by reason of the fiat cooperating faces of the lid and the up er end of the cup a tight and close joint is fbrmed, which will effectually prevent the entrance of dust or foreign substances into the oil-chamber and will effectually prevent the leakage of oil therefrom. These features of construction particularly adapt the device for application to wheel-hubs, where by reason of the exposed use great difficulty has been encountered in preventing the accumulation of mud and dust from clogging the parts of lubricators as heretofore constructed.

Having thus described my invention, what I claim is l 1. An oil-cup comprising a body having an oil-chamber therein open at its upper end, a pivot-pin extending upwardly from said body a closing-lid mounted to pivot on said pin so as to swing laterally and close the upper end of the chamber, a cap applied over the pin and confining the lid thereon and separable from the lid, and a spring inclosed by the cap and acting on the lid to hold it yieldingly in closed position.

2. An oil-cup comprising a body having an oil-chamber therein open at its upper end, a pivot-pin fixed to the body and projecting upwardly therefrom, a closing-lid having an opening to receive the pin so as to pivot thereon, a cap applied over the pin with its lower end bearing against the upper side of the lid, means for fastening the cap detachpin, and a spring encircling the pin within the cap and fastened respectively to the lid and to the cap.

3. An oil-cup comprising a neck having an opening therethrough forming an oil-chamber, and provided with a lateral extension, a pivot-pin extending from said extension and arranged parallel with theaxis of the neck, a

lid having an opening to receive the pivot-pin and movable across the end of the oil-chamher, a cap fixed to the pin and bearing at its lower end on the lid, a cling the pin within the cap, and acting on thelid to hold it yieldingly in closed position, and a stop device for limiting the closing movement of the lid.

4. An oil-cup comprising a neck having av flat upper surface, and a lateral extension having its upper surface fiat and forming a continuation of that of the neck, a lid pivoted on the extension on an axis parallel with that of the neck, and a spring acting on the lid and tending to hold it yieldingly in closed position over the oil-chamber, said lid having a stop-lip adapted to encounter the pack and limit the closing movement of the 5. An oil-cup comprising a neck having an opening therethrough constituting an oilchamber and having a lateral extension, a l d in the form of a flat plate provided with an extension having an opening, a pivot-pin rising from the extension on the neck and proj eoting through the opening in the lid, a confining-cap fitting the end of the pivot-pin and bearing at its lower end against the extension on the lid, means for fastening said cap to the pin, a spiral spring encircling the pin within the cap and fixed at one end to said cap and at its other end to the lid, said spring being under tension and acting to hold the lid yieldingly 'n closed position over the oil-chamber, said lid having a stop-lip adapted to encounter the neck and limit the closing movement of the lid, and a projection on the lid for swinging the same on its axis.

In testimony whereof I hereunto set my hand, this 2d day of June, 1906, in the presence of two attesting witnesses.
